@Spyder7, I removed all my comments just to show you how bad yours were.. Telling me about the grow light I told you I also bought.. like your writing paragraphs of useless info.... a 10W cob is still a cob.. but your gonna argue that as well.. like Look at yourself bro.. who are you trying to convince?

@DeadwebsiteBoringcommunity,you said ppfd = more yield "simple as that." All I did was point out that it actually isn't that simple and the "I'm just gonna grow more than you" is not a counter argument unless you are like 5. Whatever dude.

@DeadwebsiteBoringcommunity, in theory, "ppfd=yield" until you take into account other factors. One factor is the growing room. If you put my light into a black nylon tent without the reflective walls, so that you had zero reflectivity, you're not going to get the same yield I'll get in a grow tent with mylar even though the PPFD is the same. And I've read that the mylar in a modern tent is so good that it multiplies your PPFD by 25-33% depending on type and how much its reflecting (how close it is to the light). Other factors are humidity and heat. Both can impact yield all by themselves. So can grow techniques and nutrients. So you're being reductionist to the point that you're wrong - there are too many other variables that have nothing to do with pppf but will impact yield. There's truth to what you say to a point, but not to the degree you make it so I disagree. That's the problem with reductionist reasoning: it is too simplistic and it does't take into account variables that matter.

@Spyder7,thank you for the info. I'm happy with my light heights, I have 2 600w cob cree actual w is 115w at wall and the light meter has me at an optimal height. I just was curious if your grow took extra time. I don't mind waiting it'll be worth it. Again thank you

@MRwick1, all is going well; this grow is a few days into week 4 and I'm about to update my diary, though there's not much to add of note this week yet. I think CKS is simply off with the 7 week estimate they give. I made some mistakes that grow that definitely slowed it down, but that seed was a race horse compared to this one (partly because it didn't have a fungus infection like this one developed); this plant is a few days behind my other plant which sped through veg but stalled in flower. 7 weeks may be possible if you use 12/12 from seed with bloom nutes from first feed (skipping veg completely) and then harvest at the earliest possible time, and do it all under optimal circumstances: CO2 enrichment, commercial lighting, etc. For the rest of us who are not master growers, not using CO2, and not doing 12/12 from seed, then 10-12 weeks is more realistic if there's no setbacks. That's also the feeding schedule I'm using: Weeks 1-4 Veg nutes (my plant hasn't shown any pre-flowers yet on day 23 this grow); Weeks 4-10 Flower nutes Week 11-12 Flush After you've grown it start to finish, that timeline can be refined based on 'reading' the plant as its growing, but that's a more realistic timeline. In my first grow, I stalled it a couple times in flower by not giving it enough potassium and not lowering the light as low as I needed to, until very late in the grow (so for a couple weeks photosynthesis was slow and that was on me). If you're only seeing flowers in week 6 I'd check that you're giving it enough light - I know there were times where I erred on both sides that grow and again this grow. At any rate, you still have 6-8 weeks of flower ahead of you. If it goes another 8, you'll have company in the 14 week club as mine took that long so I wouldn't sweat it. It produces a really nice high, and if you can get the humidity down to 30% or under the final week, you'll also get some very frosty bud (some of the frostiest bud I've ever seen came from that first grow).

@DeadwebsiteBoringcommunity, that's an excellent graph. I added it to my '420 bookmarks' with my other reference stuff. It reminds me of an excellent illustration I found for diagnosing nute toxicity/deficiency: https://www.loudclouds.co/wp-content/uploads/2016/07/marijuana-deficiency-chart-jorge-cervantes.jpg

@DeadwebsiteBoringcommunity, its a surprisingly powerful little light for its rating - that's something I didn't appreciate until I noticed lights pulling 50 watts but rated as 300W LEDs, and understood how they could claim that. I like how movable it is: hung on a pulley, you can outmaneuver it so that you can concentrate that big center LED on whatever part of the plant you want to. Doing that was an L:ST "cheat" that let me create a nice flat even canopy in a small tent with just LST (plus defoliation in week 6 because the plant was so dense with thick growth from this light's penetration).
